declare variable code example

Example 1: javascript declare a variable

//choose the best for your solution
var myVariable = 22; //this can be a string or number. var is globally defined

let myVariable = 22; //this can be a string or number. let is block scoped

const myVariable = 22; //this can be a string or number. const is block scoped and can't be reassigned

Example 2: how to declare variables javascript

//variables are a way to easily store data in javascript
//variables are declared by the var keyword, example...
var x = 10;
//or
var dog_name = "daisy";
//which can also be written as 
var dog_name = 'daisy';
//same thing with single quotes and double quotes

Example 3: how to define variables

-Use pm.globals to define a global variable:

pm.globals.set("variable_key", "variable_value");

-Use pm.collectionVariables to
define a collection variable:

pm.collectionVariables.set("variable_key", "variable_value");

-Use pm.environment to define an environment
variable (in the currently selected environment):

pm.environment.set("variable_key", "variable_value");

-You can use unset to remove a variable:
pm.environment.unset("variable_key");

-Defining local variables
Local variables are temporary values you set
in your request scripts using the following syntax:

pm.variables.set("variable_key", "variable_value");

You do things!

Example 5: how to make variable

local UIS = game:GetService("UserInputService")
local RS = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RemoteEvents = ReplicatedStorage.RemoteEvents
local Player = game.Players.LocalPlayer
local Camera = workspace.CurrentCamera
local DefaultSize = script.Parent.Size

function determineClosest(EggsAvailable)
	local CurrentClosest = nil
	local ClosestDistance = script.Parent.MaxMagnitude.Value
	for i,v in pairs(EggsAvailable) do
		local Egg = workspace.Eggs:FindFirstChild(v)
		local mag = (Egg.UIanchor.Position-Player.Character:WaitForChild("HumanoidRootPart").Position).Magnitude
		if mag <= ClosestDistance then
			CurrentClosest = Egg
			ClosestDistance = mag
		end
	end
	return CurrentClosest
end

RS.RenderStepped:Connect(function()
	if Player.Character:FindFirstChild("Humanoid") then
		if Player.Character.Humanoid.Health ~= 0 then
			local EggsAvailable = {}
			local CameraRatio = ((Camera.CFrame.Position - Camera.Focus.Position).Magnitude)/11
			script.Parent.Visible = false
			for i,v in pairs(game.Workspace.Eggs:GetChildren()) do
				local mag = (v.UIanchor.Position-Player.Character:WaitForChild("HumanoidRootPart").Position).Magnitude
				if mag <= script.Parent.MaxMagnitude.Value then
					EggsAvailable[#EggsAvailable+1] = v.Name
				end
			end
			if #EggsAvailable == 1 then
				local Egg = workspace.Eggs:FindFirstChild(EggsAvailable[1])
				local WSP = game.Workspace.CurrentCamera:WorldToScreenPoint(Egg.UIanchor.Position)
				script.Parent.Visible = true
				script.Parent.Position = UDim2.new(0,WSP.X,0,WSP.Y)
				script.Parent.CurrentTarget.Value = Egg.Name
			elseif #EggsAvailable > 1 then
				local Egg = determineClosest(EggsAvailable)
				local WSP = game.Workspace.CurrentCamera:WorldToScreenPoint(Egg.UIanchor.Position)
				script.Parent.Visible = true
				script.Parent.Position = UDim2.new(0,WSP.X,0,WSP.Y)
				script.Parent.CurrentTarget.Value = Egg.Name
			elseif #EggsAvailable == 0 then
				script.Parent.CurrentTarget.Value = "None"
			end
			script.Parent.Size = UDim2.new(DefaultSize.X.Scale/CameraRatio, DefaultSize.X.Offset, DefaultSize.Y.Scale/CameraRatio, DefaultSize.Y.Offset)
		end
	end
